| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Catalyzes xyloglucan endohydrolysis (XEH) and/or endotransglycosylation (XET). Cleaves and religates xyloglucan polymers, an essential constituent of the primary cell wall, and thereby participates in cell wall construction of growing tissues By similarity. |
| Catalytic activity | Breaks a beta-(1->4) bond in the backbone of a xyloglucan and transfers the xyloglucanyl segment on to O-4 of the non-reducing terminal glucose residue of an acceptor, which can be a xyloglucan or an oligosaccharide of xyloglucan. |
| Subcellular location | Secreted › cell wall Probable. Secreted › extracellular space › apoplast Probable. |
| Tissue specificity | Predominantly expressed in green siliques. Ref.4 |
| Post-translational modification | Contains at least one intrachain disulfide bond essential for its enzymatic activity By similarity. |
| Miscellaneous | In contrast to group 1 and group 2 endotransglucosylase/hydrolase proteins, it may not contain the ligase activity, and may catalyze endohydrolysis xyloglucan polymers only. |
| Sequence similarities | Belongs to the glycosyl hydrolase 16 family. XTH group 3 subfamily. |
| Sequence caution | The sequence AAM63851.1 differs from that shown. Reason: Erroneous initiation. |
